DUST RECEPTACLE FOR VACUUM CLEANERS.

Application filed February 7, 1921. Serial No. 443,146.

To all whom 1'2 may concern Be it known that we, FRANK J. Dnu'rson, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, and Emroivo FARKAS. a citizen of the Republic of Hungary, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Dust Receptacles for Vacuum Cleaners, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

()ur invention relates to vacuum cleaners, and particularly to a new and improved receptacle for the dust and dirt co lected by such cleaners. More particularly. ourinvention relates to such a receptacle from which the contents may be easily and effectively discharged without the necessity of detaching the receptacle from the machine. The invention is an improvement, in apparatus of this character, upon the invention shown in application for U. S. Letters Patent Serial No. 382,107, filed May 17, 1920, by Frank J. Deutsch.

The annexed drawing and the following description. set forth in detail certain means embodying the principle of our invention, the disclosed means, however, constituting but one of the various mechanical forms in which the principle of our invention may be applied.

In said annexed drawing:

Fgure 1 represents a side elevation of our improvement, with the body, motor and other co-operating parts of any vacuum cteaner of standard design, in connection with which our invention is utilized;

Figure 2 represents a bottom plan, taken from the plane indicated by the line IIII, Figure l;

Figure 3 represents a top plan, taken from the plane indicated by the line III III, Figure 1;

Figure 4 represents a rear elevation, taken from the plane indicated by the line IV IV, Figure 1; and

Figure 5 represents a vertical, transverse section, taken in the plane indicated by the line V-V, Figure 4.

Referring to the annexed drawing, in which the several parts are indicated respectively by the same ordinals in the different figures, a vacuum cleaner of standard design is indicated by the ordinal 1. This cleaner [5 provided with a handle 2 which forms a support for our invention, although 0b- VlOllSiY, any suitable support, in connection with the cleaner 1, might be provided. The cleaner 1 also has the usual dust-bag? Our invention is designed to form a continuous chamber with this dust-bag 3, and to thisend the bag 3 is shown formed with a section {3' of a size suitable to register with the adacent portion of our invention. This inventlon consists of a metallic receptacle 4 having a body portion 1 and a dust-dis charging door 5, and formed with an upper open end 4 adapted to register withan opening 3 formed in the section 3 of the dust-bag 3, so that the metal receptacle 4 means of hub members 11, a pair of arms 7, 1

which arms 7 are also respectively secured to the sides of the receptacle door 5 by means of the rivets 8. Mounted upon the shaft 6 and adjacent the ends thereof are a pair of coil springs 10 bearing at one end upon the arms 7 and adapted normally to hold the door 5 closed. An annular groove 4: is formed in the bottom face of the body portion 1 of the receptacle 4 and within said groove is disposed a fabric or other packing ring 12, against which the periphery of the door 5 bears.

The box 4 is mounted upon any convenient part of the machine and is shown herein mounted upon the handle 2 by means of an arm 13 secured to one side of the boX 4, and also secured, by means of rivets 16, to a strap 15 tightly encircling the handle 2, as plainly shown in Figures 2 and 3. Pivota-lly mounted on one end of the shaft 6 is a lever 17 having a tread portion 18 at its outer end. Secured to the extreme inner end of the lever 17 is a pin 19 adapted to contact with one of the arms 7, thus effecting the opening movement of the door 5, when the tread portion 18 is depressed.

It is evident from the foregoing description that, whenever it is desired to empty the receptacle 4 of its dust contents, the door 5 thereof can be opened by depressing the lever 17 through the medium of the tread portion 18, the contents of the receptacle dropping by gravity therefrom, and, upon the release of the tread portion 18, the door 5 will automatically close under the tension of the springs 10.

What we claim is:

1. In a dust-receptacle for vacuum cleaners, the combination of a fabric bag; a dustdischarge opening formed therein; a metallic box having an open side registering with said discharge opening; a support for said box; a door controlling the discharge from said box; means normally holding said door closed; and means including a foot lever for opening said door to discharge the dust.

2. Ina dust-receptacle for vacuum cleaners, the combination of a fabric bag; a dustdischarge opening formed therein; a metallic box having an open side registering with said discharge opening; a support for said box; a door controlling the discharge from said box; means normally holding said door closed; and means for opening said door to discharge the dust, including a shaft and a support in which the same is suitably mounted, an arm mounted on said shaft and secured to said door, and a foot lever adapted to actuate said arm.

3. In a dust-receptacle for vacuum cleaners, the combination of a fabric bag; a dustdischarge opening formed therein; a metallic box having an open side registering with said discharge opening; a support for said box; a door controlling thedischarge from said box; means normally holding said door closed; and means for opening said door to discharge the dust, including a shaft mounted in said box, a pair of arms mounted on the ends of said shaft and secured to the sides of said door, respectively, and a foot lever adapted to actuate one of said arms.

4. In a dust-receptacle for vacuum cleaners, the combination of a fabric bag; a dustdischarge opening formed therein; a metallic box having an open side registering With said discharge opening; a support for said box; a door controlling the discharge from said box; ashaft journaled in and transversely of said box; a pair of arms mounted on the ends of said shaft and secured to the sides of said door, respectively; a pair of coil springs mounted upon said shaft and bearing upon said arms, respectively, normally to hold the door closed; and a foot lever adapted to actuate one of sa d arms to open the door to discharge the dust.

5. In a dust-receptacle for vacuum cleaners, the combination with the operating handle of the cleaner; of a fabric bag; means forming a metallic receptacle supported by the handle, intersecting the wall of the bag so as to form a continuous chamber therewith, and having a door controlling the discharge from said receptacle; means normally holding said door closed; and a foot lever adapted to open said door to discharge the dust.
